| Abstract |
This paper describes a simplified novel sensorless control of an SRM by detecting a current level during the non-excitation period. Since the inductance of the motor is a function of the rotor position, a simple detecting current pulse caused by a regulated pulse voltage gives information on the rotor position. In this paper, a small detecting pulse current is compared to the preset current levels which are proportional to turn-on and turn-off positions. And the comparison results are used for the excitation of the next phase. The suggested method is verified by some simulations and experimental tests. |
